I'm having similar experiences. I find an old but decent bike left out for garbage at one house so I fix it up and give it to someone down the street who's looking for a bike to ride. I've now shifted numerous bikes around the neighborhood. Sometimes the original owner sees it spruced up and working perfectly and takes back an old friend. I have to get rid of them because I don't have room to store them anywhere (already more than a dozen bikes hanging in the garage and workshop). Overall the neighborhood is riding bikes more and more. It is definitely contagious. And I get the experience of working on all these bikes. When someone tries to pay me I tell them I only accept payment in liquid form. And sometimes I get a really expensive bottle of wine (it is a slightly upscale neighborhood), which is nice. It feels good too.
